Flash floods result in significant damage to the society and economics of a particular country. These are serious issues in built-up areas, where the drainage network is weak and unable to survive a heavy flood event. Knowledge of the areas which are vulnerable to flood risk is mandatory to apply techniques to reduce the risk. Identifying flood is difficult in basins which are not gauged. The present study aims to define a manageable procedure for a delineation of flood plain areas. There are many tools for detecting the flood hazards areas effectively and economically like FLO-2D Integration tool, Flood Risk tool, Geomorphic Flood Area Plugin, and QGIS with HEC RAS. The QGIS tool, Geomorphic Flood Index (GFI), is the worthiest tool to identify flood vulnerable areas if the areas are large and data-deficient. In terms of data and calculating cost, this tool provides good accuracies with low requirements.
